Please, pay a visit to the foreign secretary and, quoting this directive, make the following declaration:
The government of Great Britain has already received notifications calling its attention to attempts made in England to fan a campaign for purposes hostile to the Soviet Union basing on the long exposed lies spread by Goebbels' propagandists about the so-called "Katyn issue". In a démarche submitted by the Foreign Ministry of the USSR to the British Embassy in Moscow on September 13, 1972 with the purpose of its being conveyed to the British government it was stressed that the scandal connected with the construction of a "monument" to the Katyn victims in London, inspired by certain circles, arouses fully justified indignation in the Soviet Union.
[...] Particularly insulting is the character of inscriptions, which - according to reports, have been approved for the said "monument". They distort in a vulgar manner the historical facts about the real culprits of the Katyn tragedy and they actually serve to reproduce the despicable lies that the Nazis began to spread during the Second World War in an effort to cover up the atrocious crimes of Gestapo henchmen which the entire world knows about.
[...] Moscow expects the British government to take proper steps to put an end to this campaign hostile to the Soviet Union, which has been developing in connection with the construction of the so-called "monument" to the Katyn victims [...].
